3 Ways Water Can Damage Your Chimney

Water is one of the most devastating enemies of chimneys. Since masonry materials – such as brick, stone and concrete – used to build chimneys are porous, these exterior components are highly susceptible to water-related damage. Here’s how water can affect your chimney.

1. Chimney leaks: Common masonry materials like brick, stone and concrete naturally absorb water when they come into contact with it. While the water alone can weaken the structure of these materials, the water trapped within the masonry is even more harmful when it continues to freeze and expand over time. It can cause fractures and leaks. It is even worse when water seeps into the very structure of your home.
2. Weakened structure: As water freezes and expands within the chimney masonry, it encourages the chimney structure to deteriorate faster. Mortar joints become soft and start to disintegrate while bricks can split and collapse.
3. Mold and mildew growth: Mold and mildew thrive in damp environments. If there is trapped moisture, it is only a matter of time before mold and mildew ensue. Water intrusion through the chimney can prompt fungus to grow and spread on the exterior of the chimney. This causes discoloration, which is unsightly.

How Can You Protect Your Chimney?

In order to preserve the strength of your chimney, the most important thing to do is prevent water or moisture from entering the chimney masonry. Most professionals recommend applying a waterproof sealer to protect the chimney from water-related damage and its effects. For optimal performance, waterproofing should be reapplied at least once every five years.
